Sunnat radiator selection of the industry's highest standards of copper content of 99.99% of the high-quality copper and 6063 aviation-grade titanium magnesium aluminum; Senat copper aluminum composite materials, smooth without impurities, high temperature and pressure, plasticity 3, we use the exclusive 3D second-order expansion tube technology, copper, aluminum composite, so that the two materials to achieve molecular-level close fit, to achieve the heat in the long-term, The lossless conduction between the two materials, compared to the traditional single expansion process radiator heat dissipation increased by 15% or more;
